We are trying to use a package released by a commercial entity for use with one of their reporting software. I think it was closed source at one point then they converted it to a "Community" release and re-released it as a open source project on Github.
Now, the problem I'm facing is that the project is released under Apache 2.0 license but when I looked through the sources, some of the files under the "lib" folders have "CC BY-NC-SA" license at the top of the source file like this:
/**
* CC BY-NC-SA License
* (...) by (...) is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
* Based on a work at http://github.com/(...)
*
*/
How does this work in terms of licensing? Does this make the whole project Non-Commercial? Or, does this get overridden by the Apache 2.0 license at the project level? By the way, the author of the source mentioned above is also part of the team that released the top level project.
